Dock disappears randomly on macOS Tahoe 26.0

I got this issue right after update. Switching toggle to disable/enable auto hide fixed the issue.

press command + option + d

to quickly make the dock reappear again. That way it's less of a nuisance.

Hope this gets fixed asap, it's really really annoying.

I have the same issue. I have found that if you press a key like the ESC key to go out of screen saver mode the problem does not happen but if you use the mouse it does.

I seem to have it working, but only because I moved the dock to the bottom, which is NOT where I want it. All the "kill dock" or Command Option D things are temporary

Since I updated to 26.1, the dock issue has been resolved for me.

try in terminal.

defaults write com.apple.Dock autohide-delay -float 999 && killall Dock

Has anyone else run into this?

Starting with second statement first

No Disappear Dock(s)

Yes, the dock will disappear if applications are put in Full Screen Mode

Mouse over bottom where the Dock should be - it pops up as expected

What is occurring, on you machine, seems by all accounts to be localized and unique to your computer

The OP reported that the problem with the Dock disappearing when not expected to has been resolved with 26.1.

In any case, the above command may have unintended consequences.

It should make the Dock be virtually invisible permanently, if auto-hide is true; and should have no effect otherwise...

You are basically declaring that when pressing the cursor against the edge where the Dock is, a delay of 999 seconds, or 16 minutes and 39 seconds, will occur before the Dock appears...

I'm having the same issue so I have disabled the screen saver. Lets hope there is a fix soon

I lost my dock this morning on power up, so I don't think my problem is related to the screensaver's activity, unless it's in the background somehow.

The dock failed to appear after an unusually long start-up time. Tahoe has been pretty slow to boot every session, but this morning it was especially so.

Please file a bug report / submit your Apple Feedback here: Product Feedback - Apple

Have you reported it to Apple via Feedback - macOS - Apple.  Unless a rather large number of users report it Apple won't consider it to be a bug. So everyone who experiences this report it to Apple.

Based on these logs it looks like the doc is told to auto-hide regardless of what the config is set to when the display either screen-saves or sleeps; I didn't get the bug to trigger while following the log (of course) but could extrapolate that some specific mechanic is taking place that causes the auto-hide disable call to either get missed or not happen.

I've experienced a similar issue. I hope they resolve it, as the Dock disappears after waking from the screensaver, even though it's set to always show. It's quite annoying and difficult to get it back. Thanks for sharing the Command-Option-D shortcut – it makes things much easier. However, Apple, please fix this seemingly minor yet very frustrating problem.

This helped me since the dock easily moved to my second screen and went in to hiding. With the command it stays put on my main screen (Mac M1) when opening an app on my 2nd screen.

Before using the command set your dock NOT TO AUTOHIDE, otherwise it will stay hidden for 999 secs !
